WIRE-JOINT.

SPECIFICATION forming part of Letters Patent No. 387,447, dated August7, 1888.

Application filed October 25, 1887. Serial No. 253,387.

To all whom it may concern.-

Be it known that 1, WILLIAM A. REDDIoK, of Niles, in the county ofBerrien and State of Michigan, have invented a new and usefulImprovement in Wire Joints, of which the following is a specification.

My invention is in the nature of a peculiar wire-joint, or joint forconnecting sections of wire so as to construct thereof strong skeletonframes for various purposessuch as toy bedsteads, window and doorgratings, and kitchen utensils, 8m; and it consists in a joint formed bycutting away one side of the end of the wire to or nearly to its middleline, then bending this reduced portion around another section of wire,with the flat face of the cut section next to the wire grasped thereby,and cementing these parts by tinning the joint by immersion of thearticle in a tinning-vat, as hereinafter fully described.

Figure l is a side view of one pattern of frame constructed with myimproved joint. Fig. 2 is a side View of another pattern; Fig. 3, a sideView of a modification of the joint. Fig. 4 is a sectional View of thejoint, and Fig. 5 shows the blank-Wire sections in different stages offormation before making the frame.

In forming the joint, the section A of the wire which is to form the eyethat grasps the other section is by suitable dies bisectedlongitudinally for a short distance from its end, a piece, A, Fig. 5,being completely out out therefrom. An eye is then partially formed bybending this reduced end, as seen at A in which the fiat side forms theinner periphery of the eye. This eye is then bent around the other wiresection, B, preferably at right angles, as in Fig. 4, and the eye isthen made to closely clasp the section B with its flat side, whichthereby forms a sleeve which stiffly holds the parts together. After thearticle is thus temporarilyjoined, the whole frame is dipped into atinning-vat and the joints are solidly closed by a filling, a, oftin,which conmeets the parts as strongly as if they were homogeneouslyconstructed of a single piece.

I am aware that it is not broadly new to tin wire articles after theyare made, and that it is not broadly new to reduce the end of an ar- (Nomodel.)

ticle that is to have an eye formed on it. There is, however, a newresult attained when a bisected wire is bent to form an eye aroundanother section and then tinned, in that the joint is formed by a rigidsleeve which is longer than the diameter of the wire, (to the extent oftin filling a,) and this not only gives great strength and rigidity tothe joint, but the joint does not look large and clumsy, as it does whena round (uncut) Wire is bent around another. Furthermore,a very muchless quantity of tin is required, as there is not the same open space inthe joint to be filled by the tin, and the tin adheres better and doesnot run down and cool in unsightly drops.

In Fig. 3 is shown a modification of the invention in which across-joint is made, which makes one wire to appear to cross and extendbeyond the other. In this case it is only necessary to cut the ends ofthe wire twice,one cut reducing the end to half its cross-section, andthe other out at right angles reducing it to onequarter of itscross-section. The quartered ends are then bent into separate eyes thatlie adjacent to each other, as in Fig. 3, and when tinned appear toform, and do in fact make, thasame joint.

I do not limit myself to any size of wire, but may use it of such largecross-section as to constitute stout rods for window and door gratings,picket fences, 8:0. I may also use zinc or other metal for thesuperficial coating.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

A wire frame having a rigid joint composed of two sections of wire, onehaving its end bisected longitudinally and the flat side thereof bentadjacent to and around the other section, and a cementing coat of moltenmetal applied over the whole, substantially as and for the purposedescribed.

The above specification of my invention signed by me in the presence oftwo subscribing witnesses.

WILLIAM A. REDDIGK.
